I have looked through my files and yes, did find the etui, manufactured by well known Skipper Greenwade. As said, at this time it housed an "common", original H�RSTER leader dagger with all proper accoutrement.
Has been offered by TMJRB&M in 2008 from where I have saved the pic. If there are problems concerning the pic plese delete it.
Regards,

"Never look for sqare eggs" as a late owner of an original FHH-dagger used to say.
